Question

如何在.net中获取checkboxlist中选中的值，每个值中间用逗号隔开，我做的在最前面多了一个逗号

protected void Button1_Click(object sender, EventArgs e)
{
Panel1.Visible = false;
Panel2.Visible = true;

for (int i = 0; i < CheckBoxList1.Items.Count; i++)
{
if (CheckBoxList1.Items[i].Selected == true)
{
Label1.Text += CheckBoxList1.Items[i].Value+"#";
}
}

}
}
我用的有容器

Answer 1

protected void Button1_Click(object sender, EventArgs e)
{
string s = "";
foreach (ListItem li in CheckBoxList1.Items)
{
if (li.Selected) s += li.Value + ",";
}

Label1.Text = s.TrimEnd(',');
}
